Holding device for battery cells

Abstract

A holding device for battery cells forming a high-voltage module that can be used for electrically driven motor vehicles includes an insulation plate provided with a pattern of recesses for each of the battery cells, the pattern of recesses includes positioning supports for the battery cell and flow grooves for an electrically insulating adhesive mass to be introduced.

The invention claimed is: 
     
         1 . A holding device for a plurality of battery cells for a storage device module which is usable in electrically operated motor vehicles, the holding device comprising:
 an insulating plate provided with a recess pattern for a battery cell of the plurality of battery cells,   wherein the recess pattern comprises an opening in the insulating plate into which the battery cell of the plurality of battery cells is inserted, positioning supports for the battery cell of the plurality of battery cells, and flow grooves for introduction of an adhesive, and   wherein the flow grooves extend continuously from the opening in the insulating plate.   
     
     
         2 . The holding device according to  claim 1 , wherein the positioning supports are configured such that contact between the battery cell of the plurality of battery cells and a cooling plate is prevented. 
     
     
         3 . The holding device according to  claim 2 , wherein the flow grooves are configured to ensure that a cavity between the battery cell of the plurality of battery cells, which lies on the positioning supports, and the cooling plate is completely filled with the adhesive. 
     
     
         4 . The holding device according to  claim 1 , wherein the flow grooves are formed as evenly distributed knob-shaped recesses in the insulating plate. 
     
     
         5 . The holding device according to  claim 1 , wherein the positioning supports are formed in the insulating plate as evenly distributed depressions in a form of spacers between the battery cell of the plurality of battery cells and a cooling plate. 
     
     
         6 . The holding device according to  claim 1 , wherein a number of the flow grooves is a multiple of a number of the positioning supports, and the multiple is at least 2. 
     
     
         7 . The holding device according to  claim 1 , wherein the positioning supports and the flow grooves are arranged alternately in the recess pattern in equal numbers. 
     
     
         8 . The holding device according to  claim 1 , wherein each positioning support is directly adjacent to one of the flow grooves. 
     
     
         9 . The holding device according to  claim 1 , wherein the adhesive is introduced via the flow grooves with an excess which contributes to lateral support. 
     
     
         10 . A vehicle comprising a storage device, which comprises the holding device according to  claim 1 .
